Definitions
- the invention relates to a method for integrating an alarm notification system into a telecommunication facility via a Telecommunications network connection.
- control takes place in telecommunications establishing a communication link using protocols, which between, for example, telecommunications terminals in the telecommunications network can be exchanged. described these operations are carried out by the signaling protocols. Consequently must before a message from a terminal to a called Terminal is sent, first a connection between them both facilities are manufactured. Independent of The connections become the topology of a telecommunications network a telecommunications system of telecommunications systems manufactured.
- the basic signaling mechanisms are not only used to set up and clear telecommunication connections but also to transmit information to the controller of performance features. Simple examples of this are number and name display and call forwarding.
- the disadvantage is that in the basic processes of establishing a connection the connection is always maintained that first came about in time.
- the invention has for its object a method for transmission of signaling within a telecommunication system to further develop that notes regarding the priority of establishing a connection can be transferred, the internal process sequences of the performance feature trigger for priority control, as well as a device to demonstrate the implementation of the procedure.
- the task is accomplished by a method and a device solved where high priority calls from an alarm system in the form of alarm messages signaled and corresponding signals are generated.
- An essential point of the invention is that it Alarm notification system via a standardized QSIG interface is connected to a telecommunications system.
- the QSIG standard contains logs that are typically a connection concern between two telecommunication systems.
- a telecommunications system is a device that Telecommunication terminals or a communication network to one another communication network, usually ISDN, connects. Furthermore, a telecommunication system has means for processing of messages transmitted over the communication network be on. Such means are in particular processors and memory.
- gateway describes the telecommunications system, in which the transition between the public Telecommunications network (DSS1) and the private telecommunications network (QSIG / PSS1) takes place.
- DSS1 public Telecommunications network
- QSIG / PSS1 private telecommunications network
- Term origin plant the telecommunication plant, which the establishment of a connection within the private telecommunications network initiated.
- Target system the telecommunications system on which the Telecommunications terminal directly or via a DSS1 trunk line is switched on, to which a connection was or will be built.
- ISDN Integrated Services Digital Network
- B channel two call lines
- D channel data channel
- the connections are set up according to a primary rate access standard with up to 30 B-channel lines (Europe) and 23 B-channel lines (North America).
- QSIG signaling at the Q reference point
- PSS1 Primary Integrated Signaling System Number 1
- the standardization takes place on an international level through ISO / IEC and in Europe through the ETSI and ECMA, one mutual harmonization of standards is sought.
- QSIG is open to manufacturers of telecommunications systems. Allows hence in particular the signaling and thus communication between telecommunication systems of different Manufacturers, provided that these telecommunications systems according to QSIG signal.
- QSIG or PSS1 define an ISDN (Integrated Services Digital Network) for the participants of a private communication network.
- ISDN Integrated Services Digital Network
- Protocol elements are called Application Protocol Data Unit (APDU).
- APDU Application Protocol Data Unit
- the four protocol elements are: RO-Invoke, RO-Return-Result, RO-Return-Error, RO-Reject.
- the ROSE protocol elements are created using the FACILITY information element transfer.
- the FACILITY information element is either with basic messages (messages that a Control connection establishment and disconnection), such as SETUP, ALERT, CONNECT, PROGRESS or DISCONNECT or, if no basic messages are available, with the one to be used then FACILITY message.
- Multiple ROSE protocol elements can be contained in a FACILITY information element.
- QSIG is based on the D-channel protocol according to the ITU-T standard for Basic call and for the supplementary services. This ensures that QSIG and ISDN compatible in their performance characteristics are and ISDN applications or additional services of public ISDN networks also used in a private network can be. In addition to the ISDN supplementary services various other additions for QSIG, for example name identification and call intrusion.
- QSIG offers so-called generic functions (GF) a solid foundation, in the context of the invention - similar a modular principle - different performance features to put on the basic call.
- GF generic functions
- These can be both pure QSIG-compliant or QSIG-compliant with manufacturer-specific extensions, as well as being purely manufacturer-specific. So is QSIG a signaling protocol for the above alarms with very high flexibility.
- the open QSIG standard is used in the proposed procedure expanded by two new ROSE operations.
- a first ROSE operation "AlarmIndication” allows this Alarm system, recognizable when a connection is established to make it an alarm.
- a second ROSE operation "AlarmIndicationClear" allows this the alarm notification system, an alarm status for existing Connection, regardless of the triggering procedures of the QSIG basic call, to end.
- This ROSE operation is also omitted the "Network Facility Extension", whereupon the immediate telecommunication system connected to the alarm system processing the ROSE operation.
- An interpretation APDU is provided to add additional Information about processing unknown ROSE APDUs of the type InvokeAPDU on a target telecommunication system to enable.
- the interpretation APDU receives the value: "rejectAnyUnrecognizedInvokePdu". This ensures that a telecommunications system, that doesn't support the new feature, immediately sent a RejectAPDU to the alarm system. A further reaction of the alarm system to this will be application-specific implemented.
- a telecommunications system supports the first ROSE operation "AlarmIndication" is not, the connection from the telecommunications system triggered with the message DISCONNECT.
- This DISCONNECT message also contains a RejectAPDU as a negative receipt. An error handling of the Alarm system.
- a preferred embodiment of the method provides an adjustable one Priority level with which alarms are generated and be signaled.
- the called party can based on the (optical / acoustic) priority level displayed to him of a desired connection quickly decide whether the previous call connection should be maintained or not.
- the priority level is preferably determined by means of a optical display unit on the telecommunications terminal visual displayed.
- Terminal 1 shows a telecommunications system 1 according to the ISDN standard with an integrated QSIG network.
- Terminal 1 is connected directly to a public ISDN network, terminal 2, however, is connected to a QSIG network, which has access to the ISDN network.
- the QSIG network is used as an internal network, for example within a company.
- the telecommunications systems 2 are connected to one another via a network structure, to which a plurality of terminals 3 can be connected.
- the telecommunication systems 2 are connected to one another via a meshed network.
- network structures such as star topology, bus topology or tree topology are supported.
- Figure 2 shows a connection of the alarm system 4 to the Telecommunications system 2.
- the alarm system 4 using a QSIG interface with the telecommunications system 2 connected.
- At least one terminal 3 is connected to this.
- FIG. 3 shows a message sequence of an internal connection message with high priority between the alarm message system 4 and the telecommunication system 2.
- the called subscriber can be reached.
- the message CALL_PROCEEDING is sent from the telecommunication system 2 to the alarm system 4 and immediately thereafter the message PROGRESS, using the progress indicator "in-band-info-available-now".
- This PROGRESS message stops all timers of the QSIG basic call in the telecommunication system 2 and the alarm system 4. This creates a time vacancy for special treatments that is not available within the standardized QSIG Basic Call Timer.
- an existing other connection is temporarily interrupted and a corresponding alarm message is signaled.
- the ALERT message provided for in the QSIG standard is also dropped in the process shown.
- the called subscriber takes the Answer the call, which causes a CONNECT message to the alarm system 4 is transmitted. This answers with the message CONNECT_ACK, which is then the connection.
- a FACILITY message with the second ROSE operation "AlarmIndicationClear" transmitted to the telecommunications system. After that can the connection from the subscriber or the alarm system 4 triggered according to the standard of the QSIG Basic Call.
- Feature - is a priority level that is given Connection or with which an alarm message is generated and signaled becomes adjustable.
- This priority level can be, for example, from a hierarchy be derived within a company.
- a connection can be made with a certain priority level only by an alarm message higher priority are interrupted. It can also conversely, a connection with a certain priority is not interrupted by an alarm message of lower priority.
- FIG. 4 Another message flow of an internal connection message with high priority between the alarm system 4 and the telecommunications system 2 is shown in FIG. 4. In contrast is the called to the message flow shown in Figure 3 Participant not available. Also after the Entering a dialing information the message CALL_PROCEEDING from the telecommunications system 2 transmitted to the alarm system 4 and immediately afterwards the message PROGRESS, whereby all QSIG Basic Call timer in the telecommunications system 2 and the alarm system 4 are stopped. After the called Participant cannot be reached or the conversation does not accept or if there is an error a trigger will be given the connection through the telecommunications system 2 with a ReturnError-APDU initiated using a DISCONNECT message. Error handling of the alarm reporting system is based on this.
- a call forwarding becomes due to the error handling of the alarm reporting system initiated to at least one other internal terminal. Depending on the level of priority, there will be several Call forwarding initiated.
- FIG 5 is a message flow of an internal connection message with high priority between the alarm system 4 and the telecommunications system 2 shown. Supported in this case the telecommunication system 2 the ROSE operation "AlarmIndication" Not. After entering an election information the message CALL_PROCEEDING from the telecommunication system transmitted to the alarm system. Because the telecommunications system the ROSE operation is not supported, the Call notification of the telecommunications system 2 by an "alarm indication reject APDU" a DISCONNECT message triggered. An error handling of the alarm notification system 4 is based on this.
- the lines starting with ARGUMENT describe the data of the AlarmIndicationClear request.
- the ARGUMENT is declared as a "Choice” selection. It is either empty or contains one or more extensions.
